Abstract –The design and development of smart monitoring and controlling system for household electrical appliances in real time has been mentioned in this paper. The system principally monitors electrical appliances such as Fan, Bulb, Motor, Refrigerator, Television etc. The novelty of this system is the implementation of controlling mechanism of appliances in different ways. The developed system is low cost and flexible in operation and thus can save electricity expense of consumers.
This allows the great amount of legacy code to be reused without modification in the new applications. While considerably less powerful than newer AT90 series of AVR RISC microcontrollers, new product development has continued with the AT89 series for aforementioned advantages. Features: Compatible with MCS-51 products 8K Bytes of In-System programmable (ISP) Flash Memory-Endurance: 10000 Write / Erase Cycles 4.0 volt to 5.5 volt Operating Range Fully Static Operation: 0 Hz to 33 MHz Three-level Program Memory Lock 256*8 bit Internal RAM 32 Programmable I/O lines
Key Words: Power management, home automation, building control system, wireless sensor network, Zig-bee.
1. INTRODUCTION: It is foreseen that service and personal care wireless mechatronics system will become more and more immanent at home in the near future and will be very useful in assistive healthcare particularly for the elderly and disable people. Wireless sensor networks (WSNs) have become increasingly important because of their ability to monitor and manage situational information for various intelligent power management services .Due to those advantages, WSNs has been applied in many fields, such as the military, industry, environmental monitoring and healthcare.
Three 16 bit Timer/Counters
3. COMPONANTS AND COMPATIBILITY: The basic components used in our system are as follows: 1) Zig-bee (S2C): Day by day, wireless system demand is increasing in homes due to easy placements and its coast and also you can connect easily by phone or computer. The home automation project is used control the home appliances includes fan, air conditioner and refrigerator, etc. by sending commands through the serial communication from the computer. This project is also very useful to control the electrical appliances in the room.
The WSNs are increasingly being used in the home for energy controlling services. Regular household appliances are monitored and controlled by WSNs. New technologies include cutting edge advancement in information technology, sensors, metering, transmission, distribution and electricity storage technology, as well as providing new information and flexibility to both consumers and providers of electricity.
2. MICRO-CONTROLLER (89s52): The Atmel AT89 series is an Intel 8051-compatible family of 8-bit microcontrollers manufactures by the Atmel Corporation. Based on the Intel 8051 core, the AT89 series remains very popularly as general purpose microcontrollers, due to their industry standard instruction set, and low unit cost.
